  • Answer:

    This unit does not come with a calibration certificate nor does Onset offer calibration on this sensor.  Onset uses precision components to obtain accurate measurements.  They recommend checking it annually for accuracy by comparing it to a known value.  If the logger is reporting inaccurate data, then it may be damaged and should be replaced.
